Troubleshooting
If you encounter issues after replacing your filter, consider the following:
- Air Purifier Not Turning On: Ensure the filter is correctly installed and the bottom cover is securely closed. Some air purifiers have a safety switch that prevents operation if the cover is not properly latched.
- Filter Light Remains On: Some air purifiers have a filter reset button. Refer to your air purifier's original manual for instructions on how to reset the filter indicator light after replacement.
- Reduced Airflow or Odors Persist: Double-check that the plastic packaging was completely removed from the new filter. If the issue persists, the filter may be saturated prematurely due to extremely poor air quality, or it might be time for another replacement.
